SUBJECT:
Engine Temperature Gauge - Indicator Reads A Higher Temperature Than Actual
OVERVIEW:
This bulletin involves reprogramming the instrument cluster control (CCN)
module.
MODELS:
2005 (KJ) Liberty / Cherokee
NOTE: This bulletin applies to vehicles equipped with a 2.8L turbo diesel
engine
(sales code ENR).
SYMPTOM/CONDITION:
The customer may notice that the engine temperature gauge may indicate that
the engine
temperature is high. In hot ambient temperatures, and under certain driving
conditions of
extended uphill driving while towing a trailer, the engine temperature
indicator may indicate
slightly above the 3/4 normal operating temperature mark on the temperature
gauge (but
below the engine hot temperature markings). This condition may be caused by
an incorrect
calibration of the of the engine temperature gauge.
New CCN module software corrects the old engine temperature gauge
calibration.
DIAGNOSIS:
If the engine and the cooling system are operating correctly, and the above
condition is
present, then perform the Repair Procedure.
SPECIAL TOOLS/EQUIPMENT REQUIRED:
CH6000A Scan Tool (DRBIII®)
NUMBER: 08-043-05
GROUP: Electrical
DATE: August 11, 2005
CH7000A/7001A J1962 Cable with red DRBIII® connector
REPAIR PROCEDURE:
NOTE: Before proceeding verify that the DRBIII® software version is at level
62.2.
1. Connect the DRBIII® to the vehicle Data Link Connector (DLC)
2. Turn the ignition switch to the "ON" position.
3. Using the DRBIII® scan tool recalibrate the instrument temperature gauge.
a. Select "DRBIII® Standalone"
b. Select "1998 - 2006 Diagnostics"
c. Select "All (Except Below)"
d. Select "Body Interior"
e. Select "Electro/Mech Cluster (MIC)"
f. Select "Miscellaneous"
g. Select "Recalibrate Temp Gauge" option.
4. If the recalibration of the instrument cluster was successful, the
DRBIII® will display
the following message: "Recalibration Successful".
5. If the version level of the original instrument cluster software allows
recalibration, but
the recalibration of the instrument cluster was NOT successful, then the
DRBIII® will
display one of the following messages: "Recalibration Failed" or "Write To
Memory
Address Failed". If one of these messages occurs repeat the above steps.
6. If the instrument cluster has already been recalibrated to the correct
software version
level, then the DRBIII® will display the following message: "Gauge Already
Recalibrated - Press Any Key to Exit".
7. The DRBIII® will display the following message if the original instrument
cluster
software version level is not the correct version level for recalibration:
"MIC Software
Version Incorrect - Press Any Key to Exit".
8. Verify that the instrument cluster engine temperature gauge has been
recalibrated by
selecting the "Recalibrate Temp Gauge" option again. The DRBIII® should
display the
following message: "Gauge Already Recalibrated - Press Any Key to Exit".
9. Turn the vehicle ignition switch to the "OFF" position
10. Disconnect the DRBIII® from the vehicle DLC.
